*Updated the build and Replaced Bladed Rounds with Rifle Elementalist and Primary Merciless with Longbow Sharpshot

-Do not use Galvanized Aptitude, it stacks additively and charged shots CO Factor is only 50%

-It's one of the best bows to use [Split Flights] on since it has innate MS can get multiple stacks in 1 shot. Arguably you can use it together with Vigilante Armaments for guaranteed 4 stacks on 1st shot but I opted to stack CD for stronger bleed procs from Hunter Munitions.

-I am using this in a Warframe with Nourish or Viral Primer companion.

-Don't be too far from the target when you let if fly. Treat it like it's a shotgun. Consider using Primed Shred if you're grouping up enemies instead of Vile Acceleration.

-If you don't have Longbow Sharpshot, use Primary Deadhead and replace Serration with Bladed Rounds.

-There's a particular weird bug with Split Flights and this weapon or was it intentional? At max stacks, Horizontal Spread becomes Vertical Spread and vice-versa. Not game breaking but it's just weird. It has been like that since 2019.

Alternate build Viral Slash build with Internal Bleeding
-Replace [Hunter Munitions], [Critical Delay], Vile Acceleration, Bladed Rounds and Faction mod with: Internal Bleeding, Point Strike, Rime Rounds, Malignant Force and Hammer Shot
-With these, you'll end up with 87.5% CC and 90% SC. IDK if my math is right, If you slot in [Hunter Munitions] instead in this build, at Max Stack of Split Flights you'd have 4 Slash Procs with a chance of 5 and with Internal Bleeding it will be 5 with a chance of being 6.
-Is it worth it? In my opinon, Nope. Is it viable? yes. because you can easily proc viral too.
-if your riven gets you to 100% CC it'll be 5 slash procs even with Hunter Munitions with a chance of 6 but lower than internal Bleeding. You can scrap the idea of Internal Bleeding but up to you.
-if your riven has high%SC then TOTALLY screw this viral slash build and go non-elemental with Internal Bleeding

Alternate Slash Build with Internal Bleeding
-Assuming You have a dual positive riven that made you reach excatly 100% SC(actually impossible even with Perfect ++-, best you can [Reach] is 99.9% but close enough and this for example only) with just [Hammer Shot] as your other source of Status Chance, Replace [Critical Delay] with [Point Strike], Bladed Rounds With Hammer Shot and Vile Acceleration With Your riven. If no Riven you can actually just use Rifle Aptitude.
-on paper at best case scenario at max Split Flights MS with 100% SC, you'll do 10 slash procs but there's still a chance that it'll be lower than 10 or more than 10.
-You can also try a meme build with [Hunter Munitions] and [Internal Bleeding]. They won't cause double Slash procs and do not additively stack and can not trigger at the same time but it will increase your chance of slash procs with a miniscule amount reastically, it'll only add about 1 more proc. This meme build is more worth it if you're using the viral hybrid build and if you have outside sources of raw damage like vex armor.
